ABSTRACT:
A device and a method for the manufacturing of a three-dimensional object (3) by solidifying of layers (25, 26) of a powder material at locations corresponding to the respective cross-section of the object (3) is provided. The device comprises a recoater (24) for applying the layers of the powder material (27) in the building area (5) which is moveable across the building area (5). The recoater (24) is designed with a rigid blade (21a, 21b) which is rigidly connected to the recoater (24). For preheating the powder material (27), the recoater (24) is provided with a heating device (20, 23) which is at least partially integrated into the recoater. In this way it is possible to preheat the powder already during or prior to applying it as a layer and thereby shortening the whole building time for the three-dimensional object (3).
